基于微透镜阵列偏振探测器的噪声性能研究

偏振探测技术己经成为一种重要的探测手段，其机理研究对可见及近红外偏振探测的实际应用和结果分析具有重要的理论指导意义。随着微透镜阵列技术飞速的发展，微透镜阵列偏振探测器成为了新型的探测器。很多文献对微透镜阵列偏振探测器的研究仅限设计及光学性能分析方面，但并没有给偏振度等效噪声评价的精确理论公式。针对微透镜阵列偏振探测器模型分析了探测器尺寸、偏振片消光比、入射光源的偏振和像素间串扰等因素，给出了偏振度等效噪声的精确理论公式，并用计算机进行了模拟分析。该研究对微透镜阵列偏振探测器性能提高具有重要的指导意义。

Abstract

Polarization detecting technology has become an important means of detection, the research on its detecting mechanism has important theoretical significance and practical value, it will guide the practical application and results analysis of visible and near-infrared polarization detection. With the rapid development of micro-lens array technology, micro-polarizer array focal plane has become a new type of detector. A lot of literature on the study of the micro-lens array technology, micro-polarizer array focal plane is only involved in design and the optical performance analysis, but the exact theoretical formula for the noise equivalent degree of linear polarization(NeDoLP) was not given. The factors, such as focal plane array size, polarizer extinction ratio(ER), pixel crosstalk, and processing algorithms were analyzed aiming to micro-polarizer array focal plane. The accurate theoretical expression of the noise equivalent degree of linear polarization was given, and simulation analysis was completed with computer. The study has important guiding for improving the performance of the micro-polarizer array focal plane.
